An Integrated Methodology for Emulsified Cosmetic Product Formulation Using Integer Programming with Logical Constraints
Résumé
This work proposes the incorporation of heuristic knowledge into an optimization-based methodology to formulate cosmetic emulsions. Heuristics regarding choice of ingredients and their amounts are modelled as algebraic restrictions and if needed translation of logical conditions to algebra is performed. The more heuristics included, the more limited the design space becomes. Through integer cuts, ranked candidate solutions may then be generated. A case study of a hair conditioner is presented, being generated tens of solutions significantly better than a known prescription.
